i'm about to up the boost slightly on my twin tub, and haveing already planned for this on my other car (a 2.5 v6 twin tub mitsi) the chaps that know their onions with the VR4's have advised that the stock re-circ dump valves will likely leak as the springs and other internals weren't up to the job and are likely slightly weaker with age too.
so is this likely to be the same with the Z32?, afterall my car being an october 92 is five years older than my 97 VR4.
if so, what dump valve arrangement is best?
replace them where they, or get the hard pipe kit as per Z1 motorsport HKS thingies?
